Proliant 1850R 2 slot expansion cage

I believe that the 2 bay expansion cage is experiencing a failure. All 3 drive lights come on the moment the unit is powered up. The drive lights on the drives in the other bay do not light up until the Smart 3200 is loading. The Smart 3200 will see drive 4 (most of the time) in the cage but not drive 5.

Is there a reset that can be applied or should I start looking for a new cage?
